Patent GB-123731-A (GB)
Title: Improvements Mainly Applicable to Electric Locomotives.
Inventor: GIUESPPE PESTARINI
IPC: B60L9/00
Filed: 1919-02-14
Abstract: 123,731. Pestarini, G. Feb. 16, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Systems depending on the use of stati'c transformers.-Relates to arrangements of transformers for feeding motors for traction and other purposes. Two of the arrangements are selected for illustration. In the arrangement shown in Fig. 1, a static transformer Q is employed for supplying squirrel cage motors M, M with constant current from a direct current source at T of constant voltage. The distributor A for the transformer is rotated by a small constant speed motor C which by means of a secondary winding of the stator furnishes the low tension auxiliary current for the inside service. The distributor B of the main motors is rotated by a small motor E, the speed of which is regulated either automatically or by hand. In the arrangement shown in Fig. 2, squirrel cage motors are fed from a polyphase source through an auto-transformer. The distributor 7 for the squirrel cage motor or motors is driven by a small variable-speed motor 8, the speed of which is regulated by the operator. A nearly constant flux is maintained by adjusting the contacts 3, 4, 5 of the transformer. As these contacts should occupy definite positions corresponding to each speed of the motor 8, the adjustment of the controller of this latter motor is caused at the same time to adjust the contacts. The various other arrangements comprise systems of similar character taking power from either direct current or monophase and polyphase sources.

Abstract: 294,598. Keller, O. Meyer-, and Dreyer, A., (trading as Meyer-Keller et Cie, 0.). July 27, 1927, [Convention date]. Tubes.-In a method of continuously manufacturing autogenously welded tubes from a metal band, the band is first drawn into the form of a slotted tube, then through a. drawplate, then autogenously welded by a burner and then passed through a set of rolls which feed the tube through the machine and also finish it to size. In making thin tubes of a wall thickness of less than 0.8 m.m., the band b is drawn from a reel a by the feed and sizing rollers g, first through a sectioning die c provided with bridge pieces s, then through a draw plate d, then under a welding burner f, and finally through the rollers g. The tube is guided in its passage under the welding burner by jaws e, Fig. 1<b>. The pass of the pairs of rollers g is progressively smaller so as to finish the tube to size, to assist the feed and to prevent binding by the welding heat. When making tubes having a thicker wall the die c is replaced by a set of sectioning rolls and the jaw guide e is replaced by a pair of lateral guide rolls mounted on vertical axes. A tube cutting machine may be combined with the forming machine. The Specification as open to inspection under Sect. 91 (3 (a) states that in making thick tubes the drawplate d may be omitted. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in apparatus for single stroke signalling
IPC: E21F17/18
Filed: 1924-02-18
Abstract: 234,166. Webb, H. N. Feb. 18, 1924. Bell-operating mechanism, pneumatic. - Single-stroke signals of the pneumatic bell type for use in mines, on omnibuses, and for other purposes are effected by means of a pulse of air travelling through a tube, and according to the invention the operating piston fits loosely in its cylinder. Thus on sudden depression of the loosely fitting plunger 2, Fig. 2, either directly or through an arm acted upon by a cord, an air impulse travels along the tube 5 until it reaches a cylinder 6 where it impels a striker 7 into contact with a bell 8, a hole 9 being provided to facilitate the instant return of the striker, while a spring 15 prevents that return from causing noise. In a modification a short length of open pipe is connected to the cylinder 1 so that when the piston 2 is raised, air enters through the open pipe and in consequence of the momentum acquired thereby a compressional impulse travels along the tube. The transmitter may be connectible selectively to any one of several tubes 30, Fig. 5, a rotatable sleeve 29 serving to close all of the tubes except that opposite to the hole 31, the position of which is indicated by a pointer 29<b>. Alternatively the plunger 2 may be arranged in a separate chamber which communicates by a pipe with the interior of the sleeve 29. Several transmitters mav control the same receiver, a plug 14, Fig. 2, replacing the tee-pipe 12 when the latter is not required. For signalling in both directions a single pipe 5 may be used, the transmitters and receivers being connected to it through valves.
